Battle of Krossberg

The Battle of Krossberg was a prison breakout by Allied prisoners-of-war taking place in Krossberg, Austria, in 1943. A rescue mission launched by Captain Steven Rogers saved 400 POWs from the Hydra division's base, which was destroyed.

Background
After the Battle of Azzano, Captain Steven Rogers of the US Army was alerted that there were many Allied POWs held in a prison camp at Krossberg between two mountain ranges in Austria. Against orders, he decided to launch a solo rescue mission to free his friend, Sergeant James Barnes. He was flown over the mountains by Howard Stark and parachuted into the camp amidst anti-aircraft fire, and infiltrated the base in the back of a troop transport. He subdued many guards and made his way to the prisoner cells, where he freed them and gave them guns.

Battle
The prisoners, armed with advanced weapons made by the Hydra Nazi deep science division, fought off the Nazi German troops and captured an advanced tank. Despite many prisoners dying after Doctor Johann Schmidt set off a self-destructive bomb across the base, 400 men and the tank were returned to the US camp in southern Italy, where they returned to active duty or were allowed to return home.

Aftermath
Intelligence from Sergeant Barnes revealed that Hydra had a variety of missile sites across Europe, including one near the Maginot Line, one in the Alps, and many others across German-occupied lands. By the year's end, all of the bases were captured and Hydra was destroyed.
